Reaction Steps

To a solution of (2R,3 R,4R,5S,65)-2-(acetoxymethyl)-6-(4-chloro-3-(4-(2-oxoethyl)benzyl)phenyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate (0.35 mg, 0.61 mmol), in ethanol (10 mL) under nitrogen atmosphere, were added pyridine (0.24 mL, 3.04 mmol), and O-methylhydroxylamine hydrochloride (151 mg, 1.82 mmol). The reaction mixture was refluxed for 2 h. After completion of the reaction as confirmed by TLC, the solvent was evaporated. The crude compound was diluted with ethyl acetate (25 mL). The organic layer was washed with water (3×10 mL), dried over Na2SO4 and concentrated in vacuo to afford crude product which was purified by column chromatography (silica gel, 1.0:9.0 Acetone:Pet. Ether) to afford the title compound (80 mg, 22%).
